This series of 4 videos will cover the construction of a robust half leather binding used for library books in the 19th and early 20th century in England. The design is a combination of techniques covered in 3 books, Advanced Bookbinding by J. Kay (1932), The Thames and Hudson Manual of Bookbinding by Arthur Johnson (1978), and Bookbinding by William Matthews (1929). The characteristics are split board attachment, tight-back binding with tape supports, a wide French groove joint, minimal edge paring of leather and no paring of the joints. The minimal paring make it an excellent introduction to leather binding. This fourth video will cover covering the spine, covering the boards with cloth, and pasting down the endpapers.
